#20551 changed the condition checking if the ICU version matches the stubbed data. The change intended to enable tests on more ICU versions, but it actually has limited them. I'm still not convinced it should've been done but let's at least fix the condition. Ideal solution would be to have the latest ICU data available on travis (still not there travis-ci/travis-ci#3616).

I also needed to fix several tests.

Currently skipped tests in components depending on ICU data:

|            | 4.8.1.1 | 54.1 | 55.1 | 57.1 |
|---|---|--|--|--|
| Intl       | 488     | 488  | 7    | 6    |
| Locale     | 0       | 0    | 0    | 0    |
| Translation| 0       | 0    | 0    | 0    |
| Validator  | 69      | 69   | 69   | 0    |
| Form       | 75      | 75   | 75   | 1    |
