George Kalpakas 6bf8b1007c test(platform-browser-dynamic): make CachedResourceLoader tests more reliable (#30515)
Previously, [this test][1] would occasionally fail (e.g. on CI) with
"Template cache was not found in $templateCache". This was due to a
combination of:
1. [That test][2] (which removes the cache) being run right before the
   failing test.
2. The async `TestBed.compileComponents()` operation run in the
   `beforeEach()` block (which sets the cache) not having completed
   before the `it()` block.

This commit fixes the issue by ensuring the cache is always set, before
instantiating `CachedResourceLoader`.

This commit also moves some operations that are only needed in one test
from the `beforeEach()` block to that test's `it()` block.
