Allow using `sentry_release` or `sentry_odoo_dir` in the Odoo
configuration file.
Previously, the `sentry_odoo_dir` was never actually respected. It would
always be overridden by `sentry_release`. Even if `sentry_release` is
not set, it will use an empty value instead of using `sentry_odoo_dir`
to find the Git commit hash.
After this commit, the `sentry_release` parameter still takes
precedence. However, if `sentry_release` is not set and
`sentry_odoo_dir` is set, then `sentry_odoo_dir` will be used to find
the appropriate Git commit hash, which will be used as the `release`
value.
Both cases are covered by the added unit tests.
