tdf#125609 c14: vcl button: don't modify style directly

LO 6.4/6.3 commit d35171456bc230efdaa9426da1398b2db7fa0df8
could cause a recursive loop. ImplInitStyle RETURNS the
suggested style, while ImplUncheckAll MODIFYS the
actual style. Since the call to set WB_TABSTOP
was already redundant in this case (and many others),
I provided an option to avoid that direct modification.

An example crashing document is attached to the bug report,
which will eventually find its way into automatic crash testing.
For this particular example document, it also requires
LO 6.4 commit 5cf057c3365a0feafc8f2e4f4a9e24d69a581999
in order to trigger a crash.
