weston/tests/config-parser-test.c
Pekka Paalanen 3e94836a63 tests: add get_double in config-parser tests 
weston_config_section_get_double() was not covered with tests before.

This patch follows the testing style already present in the file.

Cannot use ZUC_ASSERT_EQ() here, because that would convert the values
to integers before comparison. Luckily, simple strict equality
comparison works here, because we are testing conversion to float, not
the results of lossy calculations.
