Fix cursor not showing in empty block preceding a table

When an empty text block precedes a table in QTextEdit, the cursor in
the said text block is drawn twice (in order to make sure that the
cursor is drawn on top of the table) with inverted colors, resulting in
nothing showing up. This commit checks for an empty block before the table
and skips the first drawing of the cursor if that's what it finds.
