Fix a case when extension less file is importing other less files

[zaggino]

I wanted to split less file my extension is using into more files, but loading failed when using valid import directives. Through debugging, I found out that some properties of file info were not filled as it should.

These are the values for file brackets.less:

currentDirectory: "file:///D:/Program%20Files/Brackets/dev/src/styles/"
entryPath:        "file:///D:/Program%20Files/Brackets/dev/src/styles/"
filename:         "file:///D:/Program%20Files/Brackets/dev/src/styles/brackets.less"
relativeUrls:     undefined
rootFilename:     "file:///D:/Program%20Files/Brackets/dev/src/styles/brackets.less"
rootpath:         "file:///D:/Program%20Files/Brackets/dev/src/styles/"

And these are the original values calculated for brackets-git.less:

currentDirectory: ""
entryPath:        ""
filename:         "brackets-git.less"
relativeUrls:     undefined
rootFilename:     "brackets-git.less"
rootpath:         "file:///C:/Users/Zaggi/AppData/Roaming/Brackets/extensions/user/zaggino.brackets-git/less/"

The fix makes fileInfo look the same way as in the brackets.less case and all references are loaded correctly.

Btw, is there a reason Brackets is still using less 1.4.2 when latest version is 1.7.0 ? The fix works for both versions and I didn't find any ill effects when upgrading to 1.7.0.

@zaggino Discussion about updating Less to 1.7.0 is in #6730.

Thanks @le717, I thought I've seen it somewhere but I wasn't sure. Anyway it's not included in this PR.

There's an Extension Utils unit test failing:

should attach LESS style sheets

@redmunds It seems my issue only relates to absolute url's. Do we have any function like FileSystem.isAbsolutePath which checks if url starts with (http|https|file):// ?

[zaggino]

I'd probably put the isAbsoluteUrl function into StringUtils.js and use that instead of file:// if there's not a better way.

[redmunds]

In thirdparty/path-utils/path-utils.js there's an isAbsoluteUrl function.

Review again please @redmunds

This comment doesn't seems to make sense. Remove both copies.

[redmunds]

Looks good. Just 1 minor comment.

[zaggino]

Done, comments removed.

[redmunds]

Looks good. Thanks for unit test! Merging.
