Reproduction steps:
1. Open the project in the attached GetMainAssetTypeAtPath_Bug.zip
2. Run the test script using the menu item 'Test/Test'

Expected result: There is no red assertion failure, and the test finishes with 'Unloading asset...'

Actual result: A red assertion message will fire

"AssertionException: The asset should not be loaded after calling GetMainAssetTypeAtPath()!
Expected: False
But was: True"
