Language hooks are not correctly loaded when configuring more than one file for default properties or for a specific locale.

For example, it is problematic to have two default properties: Language.properties and Admin.properties.
Following configuration won't work:

<hook>
    <language-properties>Language.properties</language-properties>
    <language-properties>Language_es_ES.properties</language-properties>
    <language-properties>Language_en_GB.properties</language-properties>
    <language-properties>Language_hu_HU.properties</language-properties>
    <language-properties>Admin.properties</language-properties>
    <language-properties>Admin_es.properties</language-properties>
</hook>

Steps to reproduce

1. Startup portal
2. Download last version of test-localized-portlet with modifications of LPS-64213 (more info see comments)
3. Run ant clean war in plugins/portlets/test-localized-portlet and deploy it
4. Add a single column page
5. Add Test Localized portlet to the page
6. Click on any language
   • Expected result: All of the tests in the portlet will read PASSED.
   • Wrong result: New "Add a new unlocalized language entry from a second property file of a hook" test fails
