Fix T102221: Entering editmode invalidates the driver associated with that mesh 

The regression is caused by D13824 0f89bcdbeb.

This fix follows the code from Sybren (D7785) to make object-mode
drivers from shapekey value to work. This intuitively makes sense
since the D13824 made the edit mode evaluation and ownership follow
the object mode more closely.
