When inserting math inset, put cursor selection in the correct cell
The original use case for this bug is entering an overset inset when there is a selection. The expected result was to have the selection pasted in main text, but the result was to have it in the cell. Insets already have idxFirst() that is able to set cursor to the "entry" cell of an inset. This patch introduces firstIdx(), which is the index of this cell and uses it in idxFirst() (idem for lastIdx/idxLast). As a consequence, several instances of idxFirst/idxLast can be removed. Now for the real fix: the two places where the cell in which selection is inserted seem to be: * Cursor::macroModeClose * Cursor::handleNest These two methods are changed to insert material in the entry cell instead of cell 0. idxFirst/Last methods are added to InsetMathRoot and InsetMathStackrel so that the natural entry point is the nucleus of those insets. Finallly, a typo is fixed in InsetMathNest::edit() where enter_front computation was incorrect.
