Exception is shown "Cannot access a disposed object" when using Parallelizable attribute

[bankova]

Setup in Bellatrix.Web.GettingStarted:

1. Add [Parallelizable] in classes LocateElementsTests and WaitElementsTests
2. In testFrameworkSettings.Debug.json set

"webSettings": {
  "isParallelExecutionEnabled": "true",

"processCleanupSettings": {
  "isParallelExecutionEnabled": "true"
},

3. Select in the Test Explorer in Visual Studio all tests from both classes and run them all.

Expected: All tests pass.

Actual: Only the tests from one of the classes will pass, the tests from the other will fail. The exception is:
OneTimeSetUp: System.ObjectDisposedException : Cannot access a disposed object.
Object name: 'System.Net.Http.HttpClient'.
In the log even for the tests that have passed the following is displayed:

Standard Error:

Hello Kristina,

We have just released the latest version of the framework. One of the issues resolved was the parallel execution, so please download the new source code and try again your scenario.
