Configure pytest to fail on what it should fail on (#25)

py-canon 1.3.0 puts the whole sp-repo-review PP301-PP309 set in the template:
minversion, log_level, xfail_strict, filterwarnings = ["error"], and
-ra/--strict-config/--strict-markers in addopts.

These decide whether a run *fails* rather than how it reads. Without
filterwarnings a dependency's DeprecationWarning stays invisible until the
release that removes the API; without --strict-markers a typo in a marker name
selects nothing and reports success; without --strict-config a typo in this
very table is ignored.

Applied with `preen fix pytest-config`, and the suite was run under the new
settings before this was opened -- the point of the change is that warnings now
fail, so a config that quietly breaks the suite would defeat it.
