Short description of error
Applying NonGeometrical modifiers (UVProject, DataTransfer, ...) looses shape key data if a shape key other than the basis shape key is selected.
The shapekey itself is still there, it just seems to have the same data as the basis shape key now

NOTE: seems eModifierTypeType_NonGeometrical are affected

Exact steps for others to reproduce the error
apply_modifier_NonGeometrical_shapekeys.blend

open blend
note a Basis shapekey (which is currently selected) and one other shapekey Key 1 is present
with the Basis shapekey still selected, apply the UVProject modifier (all is fine, the plane should still be in its place)
now select the shapekey Key 1
apply the UVProject modifier (plane hops in the position of the Basis shapekey, even though Key 1 is still selected and has full influence)
