test: fix failing test_delete_experiment_removes_tensorboard_files

[NicholasBlaskey]

Description

Fix failing test on main. Some other test sets the user in the token store to admin, since the test was running with a "different" cluster (aka not canonicalized so like 127.0.0.1:8080 vs http:127.0.0.1:8080) we think they are different clusters and have a different url.

Also moves this test to /cluster since backend owns experiment deletion.

This test is what likely messed with the token store (ran right before it)
