Comment (by bhutz):
There were 4 instances and were changed as follows (and re-tested).
affine_morphism.homogenize(): I made this StandardError since there are a
variety of ways that trying the lcm() can fail and they all should enter
the except block
affine_morphism.cycle_graph(): Catches TypeError when the point is not on
the scheme
projective_morphism.conjugate(): Catches the TypeError when the map is no
longer defined over the same ring
projective_morphism.cycle_graph(): Catches TypeError when the point is not
on the scheme
