Macro Browser does not respect the User Language preference

After changing the User Language preference, Macro Browser does not change accordingly

Steps To Reproduce

1. Set user's language preference to German
2. Edits a page and opens the macro browser
3. Now the user changes the language in his individual settings to "français (France)"
4. Edits a page again and opens the macro browser

Actual Behavior

While in German:

• Activity Stream Macro in Macro Browser still in English (label 1)
• Other Macro still in German (label 2)
• All label in German (label 3)

After changed to French:

• Activity Stream Macro in Macro Browser still in English (label 1)
• Other Macro still in German (label 2)
• Some label in German (label 3)
• Some label in French (label 4)

After clearing browser's cookies and caches:

• Activity Stream Macro in Macro Browser still in English (label 1). It seems that clearing the cache does not resolve the Activity Stream language.
• Macros in French (label 2)
• All label in French (label 4)

Workaround 1

Delete browser's cookies and caches
Note: workaround might not be applicable to Confluence version 6.14.0 and higher

Workaround 2

If delete browser's cookies and caches is not enough to fix the issue, restart Confluence.
