fix(hybrid-cloud): Remove redundant self._base_query() call in _apply_filters

[dashed]

The call to self._base_query() in _apply_filters() is redundant as we already make this call in _query_many() here:

sentry/src/sentry/services/hybrid_cloud/filter_query.py

Lines 105 to 113 in fc99b7b

	def _query_many(self, filter: FILTER_ARGS) -> QuerySet:
	validation_error = self._filter_arg_validator()(filter)
	if validation_error is not None:
	raise TypeError(
	f"Failed to validate filter arguments passed to {self.__class__.__name__}: {validation_error}"
	)
	query = self._base_query()
	return self._apply_filters(query, filter)
