te returns false if the key contains a dot

[Me-Phew]

Reporting a bug?

If the key has a dot (eg. a.b.c) t('a.b.c') returns a correct translation, but te always returns false

This is problematic in projects that use a flat locale files structure like:

{
  "key.exampleNestedKey": "Translation",
  "key2.exampleNestedKey.evenMoreNesting": "Translation"
}

Expected behavior

te returns true for dotted keys if they exist in the current locale
