Remove setPageScaleFactor from InternalSettings::resetToConsistentState.
Remove setPageScaleFactor from InternalSettings::resetToConsistentState.

here. The PageScaleFactor is reset in Internals::resetToConsistentState so this
should have no effect on current tests as these two are always called together.
