sw floattable, insert UI: fix default frame width when inserting a new one

Insert -> Frame -> Frame presented a dialog which stated the width of
the new frame will be 2cm, but the width was ~zero.

This is a regression from commit
9da7b1592e010928c26c43ee93b91cdd66403985 (sw: remove all uses of MM50
with (added) o3tl::toTwip, 2021-07-23). Previously the code worked
because the 2cm was speficified as MM50*4 (283*4=1132 twips), and we
compared this to the 2cm from the UI, which had no rounding errors
(283.46456692913387*4=1134 twips), and this 1132 vs 1134 meant the
dialog put the unchanged size to the output item set.  Now we don't have
rounding errors anymore, so we have 1134 everywhere, which means the
dialog doesn't specify a default size, but no other code would do it,
resulting in a frame with minimal width, which is clearly not wanted.

Fix the problem by checking if this will be a new frame, and if so, the
dialog should send the default size to the caller, even if the user
didn't customize the size.  This restores the lost 2cm default width
while keeping the rounding improvements.

This requires running the test in its own process, because the
measurement unit is only loaded once from the config and the rounding
error is not hit with the default inches.
