Fix Swift crash during start because of spellcheck code
Check that checker_ and highlighter_ are initialized before
calling them.
A crash report indicated a crash calling getMisspelledPositions()
on highlighter_ from QtTextEdit::contextMenuEvent(). This fix
should prevent this call to cause a crash.
Test-Information:
Verified that spell checking still works on OS X.
