Eskil Abrahamsen Blomfeldt 4d552815cf Fix plain text QStaticText with line breaks
The layout isn't actually created until endLayout() or setLineWidth() is
called. So in the case where this was not done, the height of the line
would be 0, thus multiple lines would be placed on top of each other, at
y == 0.

[ChangeLog][QtGui][Text] Fixed QStaticText when manually breaking lines
and no text width was set.

Task-number: QTBUG-56346
