Fix bug #5167: Correctly paint special characters in InsetMathFont

When using, e.g., a 'mathcal' inset in math, the inline completion and
other special characters like '\#', '{..}' are are painted in the
'mathcal' font as well. This is overcome by setting the mathnormal font
before painted these characters.
