[REVIEW-3-6] fix for fdo#55174, con't crash durig oox import for vba procedure names or macro names

[Markus Mohrhard]

Hey,

[1] fixes a crash that happens if we try to import a vba procedure
name or macro name as range name. The code does not create a
ScRangeData for these names and we should not try to create formulas
for them. This is a regression introduced by porting this code from
uno calls to direct calls.

Regards,
Markus
