GApplication: fix bogus testcase

We had a GApplication testcase that handled both open and commandline.
This only way that this worked was by implementing the commandline
handler without actually setting the HANDLES_COMMAND_LINE flag.

This behaviour is now invalid, so just rip out the offending part of the
test.
