Summary: Not handled exception when remove all gradient Cpoints

Initial Comment:
Using SVN 2039

Open the gradient editor dialog. Right click over each any existing triangle 
slider and select "Delete". The gradient becomes transparent. Now click on the 
area where the triangle sliders were. It crashed with this message:

glibmm-ERROR **: 
unhandled exception (type std::exception) in signal handler:
what: synfig::Gradient::find(): Unable to find UniqueID in gradient

Message:
Hmm, I don't think this is the right place to fix this. Either the erase
function should fail to remove the last cpoint or synfigstudio should not
crash when no cpoints are in the gradient. Personally I think removing all
cpoints is a valid thing to do so the crash should be avoided instead.
