demandimport: convert ignored modules from bytes -> str in extensions The default list of ignored modules are str, and test for bypassing the lazy import is `module.__name__ in ignores`, so these were effectively NOT ignored. Most of these date back to the grand byteification in 687b865b95ad, with some subsequent additions that followed the existing example. I have no idea if these modules in fact need to bypass lazy importing, but at least it follows the intent of the code.
