test(modal): Remove `ddescribe` in the $modal tests

The `ddescribe` is only executing the $modal tests. Removing it will allow
all other unit tests to run.

Fixes #2311.

This should prevent `ddescribe` and `iit` blocks in tests from being checked into the tree, as they
were in #2311.

Fixes #2180
Closes #2184
