Properly open quotes in warning

Commit 78b5c44 'Properly close quotes in warning' https://github.com/doxygen/doxygen/pull/7312 handled the case that a closing quote was missing in case of a missing closing quote.

I case the word template is missing it is possible to miss the opening quote, resulting in:
```
wxWidgets-3.1.3/src/x11/brush.cpp:66: warning: no matching class member found for
  wxBrush::wxBrush(const wxColour &col, int style)
Possible candidates:
  wxBrush::wxBrush()'
  wxBrush::wxBrush(const wxColour &colour, wxBrushStyle style=wxBRUSHSTYLE_SOLID)'
```

this is fixed here.
