Fix crash when text shaping fails
If text shaping failed for some reason (for example if the
string passed to Harfbuzz contains ignorables only), we
would return a single glyph for the whole string. But we
forgot to initialize the log clusters array, which could
cause crashes later when this was read. We initialize a
single cluster consisting of the "missing glyph" glyph to
be consistent.

[ChangeLog][QtGui][Text] Fixed a possible crash with certain fonts
