Angular unit tests can't compile on main

[Jane Sandberg]

Expected behavior: when I run `npm run test` from the eg2 directory of a running evergreen system, all tests pass.

Actual behavior: `npm run test` currently returns a compilation error on today's main.

Impact: Developers, committers, and release teams can't use the unit tests as a safety net to check for regressions, since they can't even run.

Patch forthcoming, should be some quick fixes.

Here is the branch: user/sandbergja/lp2069098-npm-run-test-failures

Here is a link: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sandbergja/lp2069098-npm-run-test-failures

To test, you can:
1. On an Evergreen server running today's main, install Firefox and Chromium
2. cd into the eg2 directory
3. Run `npm run test` -- notice it doesn't compile
4. Apply the commit
5. Run `npm run test` -- notice all 116 tests pass

Tested during a Monday code review session and signed off by me, Michele Morgan, Steven Mayo, and Scott Angel.

Fix merged to main and rel_3_13.

I've removed the targeting to rel_3_13 - as noted in bug 2070411, this shouldn't have been backported to rel_3_13.
