Don't test for DC validity in wxX11 wxDC text extent functions.

Browse Source 
The code in GetTextExtent() and GetChar{Width,Height}() works fine even for
non-initialized wxMemoryDC and the ellipsization unit test relies on this
working so simply remove the asserts which resulted in the test failures.
