Validate custom image names correctly

We currently validate the name of a new custom image across all projects. This means you can't use the same custom image name in multiple projects.

Modify the code to do validation correctly, and add UI tests to verify.

To test:

1. Create a project.
2. Create a custom image with name 'goo' in this project; it should work.
3. Try to create another custom image called 'goo' in this project; it should fail.
4. Try to create a custom image called 'core-image-minimal' in this project; it should fail.
5. Create another project.
6. Create a custom image called 'goo' in the second project; it should work.

The following changes since commit 4bb6fb30b0d660eaeaf4af134b99b2feaf0b3db2:
