fix(compiler): fix two existing expression transformer issues (#28523)

Testing of Ivy revealed two bugs in the AstMemoryEfficientTransformer
class, a part of existing View Engine compiler infrastructure that's
reused in Ivy. These bugs cause AST expressions not to be transformed
under certain circumstances.

The fix is simple, and tests are added to ensure the specific expression
forms that trigger the issue compile properly under Ivy.
