This PR is a fix of a little mistake on PR #12404.

Thanks @mvrhov for the clue! :+1:

Pass 'UTC' param cause issue on single_text date type, `null` should be passed to get the default php timezone.

Don't know how to add test for #12808 issue, do someone know how to "change" properly timezone during tests? Where can I do this?

Thanks.

#12404 removed the timezone options from DateType and TimeType, however the tests don't cover all cases and there was a bug introduced as per #12808.

This PR adds tests for the expected behaviour but will not fix the bug.

Unfortunately, it seems that the tests are being skipped in the form component on Travis (and have been for a year) - probably due to the ICU version being changed.

Remove usages of deprecated constants
Replace usages of the deprecated TypeTestCase by the new one
Fix phpdoc and coding standards

This removes the unused use statements which were not catched by
PHP-CS-Fixer because of string occurences. It also fixes some invalid
phpdoc (scalar is not recognized as a valid type for instance).

This removes the usage of deprecated constants in our code.

I'm applying this in 2.3 to make merging branches easier. This is especially needed for 2.7 because of deprecation warnings added in #13060 (warnings are triggered in this PR because of these usages)

This is complementary to https://github.com/symfony/symfony/pull/13134
