tdf#88555: band-aid fix, using GetPos/find instead of Contains

to find out whether given format still exists.

GetPos was replaced by Contains on multiple places in commit
98436c4b53639d86f261ac630c46d32e3c7b8e28 but sometimes after
series of undos/redos, vtable of some items in those format arrays
becomes corrupt and it makes dynamic_cast (as used by Contains)
fail and Writer falls flat on its face.

This is just a workaround, no idea about the root cause.
