fixup! Start a new projects: ij1-patcher
Move more tests from ij-legacy into ij1-patcher

All present tests that do not depend on ij-legacy should go into
ij1-patcher, of course, to guarantee that ij1-patcher's functionality
is maintained.

fixup! Add a class to encapsulate ImageJ 1.x instances
ij1-patcher: aggregate test utility functions into the TestUtils class

This is needed because we want to move more tests from ij-legacy into
ij1-patcher (and that project is supposed not to depend on anything
except Javassist).
