Still needs a bunch of code in net to be converted in order to get more
advantage of this for images and stuff, but meanwhile this should help quite a
bit with #13778.
Still wanted to get this in.

Fixes#11712
<!-- Please describe your changes on the following line: -->
Removed a method that seemed to duplicate already existing functionality, and returned BrowsingContextErrors in the web_handler file where panics were previously occurring.
I am not sure if I like all the unwrapping that occurs in the script thread, but the current methods are not set up to return Option/Result.
Also, should line the method on line 37 `find_node_by_unique_id` of components/script/webdriver_handlers.rs return None if the context is not found like I have it currently? Or should it return a `Result<Option...>` instead?

- [X] `./mach test-tidy` does not report any errors
- [X] These changes fix#11712 .
<!-- Either: -->
- [ ] There are tests for these changes OR
- [X] These changes do not require tests because I simply removed a method that duplicated already existing functionality. On the other part, I added better error sending instead of forcing a panic, which does not require testing to my knowledge.
