Vadim Zeitlin 5520d56222 Remove test input file in file stream unit tests only once
Don't remove the files in the test cases classes dtors, this was
inconsistent with how they were created: we either need to create the
file in the ctor and destroy it in the dtor or do both only once
globally.

Implement the second solution using the helper AutoRemoveFile instead of
a simple static bool in GetInFileName() implementations.
