[REF] server: better warnings when using --test-file

We add two warnings to make the --test-file argument more user friendly:
- one when the test file does not exist
example:
./odoo-bin -d master --test-file ./addonss/stock/tests/test_quant.py
before:
INFO master odoo.service.server: loading test file ./addonss/stock/tests/test_quant.py
after:
WARNING master odoo.service.server: test file ./addonss/stock/tests/test_quant.py cannot be found
- one when the test file is not a python file

In both cases, nothing was being tested but the server did not say why.

closes odoo/odoo#34808
