Consider insets that are chars in InsetCollapsable::getNewLabel()

This fixes the display of closed ERTs, Indexes etc. when they contain
special chars, logos or quotation marks.

(Since quotation marks in ERTs are now insets, not chars anymore,
this also fixes a bug/regression of the display of babel shortcuts
such as "= in closed ERTs; hence I consider this fix necessary for 2.3.x)
