shell32: Fix the logic in Control_LoadApplet determining when to use CPL_INQUIRE and when to use CPL_NEWINQUIRE.

Previously, the code would fail to get the name of an applet that didn't 
return an icon for CPL_NEWINQUIRE and didn't return set either idName or 
idIcon to a non-zero value for CPL_INQUIRE.

Fix this by sending CPL_INQUIRE first and loading any strings or icon 
specified and then only fall back to CPL_NEWINQUIRE if any of the 
required members were zero (i.e. CPL_DYNAMIC_RES) and then only fill in 
these fields.
