Fix caret height when inserting new inset

Browse Source 
For now, the simplest thing to do it to compute metrics in all cases
before calling setCurrentFont().

In 2.5, a better approach will be to add a new virtual function
InsetText::setFont that will set correctly TextMetrics::font_ (a cache
of the reference font).

Fixes bug #12126.
