QSyntaxHighlighter: Delay all highlights until first rehighlight
When calling setDocument (directly or through the constructor) a delayed
rehighlight is initiated. Previously, if any text was changed before
this rehighlight could run it would cancel the rehighlight, even if the
changed text only caused a new block of text to be highlighted.
Fixes: QTBUG-71307
