Test code for DEF041901 see teamtrack for more details 

Description of DEF041901:

If a memory allocation fails during CleanupStack::PushL in the NewLC, then

the destructor will be called. The destructor calls 

TTlsData::CharacterSetConverterIsBeingDestroyed(); which incorrectly frees

the thread local storage

@SYMTestCaseID          SYSLIB-CHARCONV-CT-0561

@SYMTestCaseDesc        Tests for defect number DEF041901

@SYMTestPriority        Medium

@SYMTestActions        	Tests for memory allocation failure.

@SYMTestExpectedResults Test must not fail
