Disable tests for weird ids string encoding

[jhamon]

Problem

We have a very large test matrix to check that different kinds of strings are handled properly. But we probably don't get that much value out of running these for every single PR.

Solution

Gate these tests on a boolean so I can only run these when desired instead of on every PR. It's most relevant to run them when changing dependencies or python versions.
