We can avoid the .getExpression() calls if we use a MethodInvocationTreeMatcher instead.

❗ This PR is on top of #4 ❗
In #4 we introduce additional logic to filter out invalid expressions in
UFreeIdent, see here.However, when this code got introduced in this commit c2e14f2, it broke our code.
The test cases in the
UFreeIdentTestandURepeatedTestare not "valid"/"realistic" enough and therefore results in anIllegalArgumentExceptioninASTHelpers#getSymbol(MethodInvocationTree).To make our code compatible with this change, we changed the tests to use
BugCheckers for the two tests. This way we can use the same assertions but use real expressions that are accepted byASTHelpers#getSymbol.Once we merge this PR we can also rebase #4 with
master.
