sagemathgh-39616: Fix tests with IPython 9

IPython 9 works fine with Sage at runtime but breaks some tests:

- `NoColor` should be lowercase now and throws a warning otherwise https
://github.com/ipython/ipython/commit/a796b952038faa904c5d7e5ea6c068b17e7
65790
- `input_transformer_manager.check_complete` returning two spaces
indentation was a bug caused by the `# indirect doctest` tag, which
confused the parser. This is fixed in IPython 9, we remove the `#
indirect doctest` so the test output is the same for all IPython
versions.
- Account for some addional verbosity in a couple of tests.
