Implement negative tests for `(set_once)` and `(goes)`

[yevhenii-nadtochii]

Currently, the suites for the mentioned options do not cover negative scenarios, in which the compilation should fail.

Please implement the following tests:

1. Fail when the option is applied to unsupported field types.
2. Additionally, make sure the (set_once) works well when it is applied to an external type (which comes from dependencies) like Google's Timestamp. We had a bug related to this, so better to have this positive test as well.
