Subject: A fix for the bug: it is possible to apply extrusion even if the algorithm is failed... 
X-Git-Tag: V_1.2.0~135^2~1

A fix for the bug: it is possible to apply extrusion even if the algorithm is failed to build the result.

Scenario: create a sketch, create a part, visualize all default planes, create extrusion, select a sketch, in "to" control select a perpendicular plane. An error message appears but "Apply" is enabled.
This fix disables the "Apply" button.
