cache_hashes was introduced at 8a28cc22fd to reduce the number of reload
The cache is correctly reseted when the translations content changed but did
not contain all the translation-related parameters that are, however, stored
in the session_info
This commit fixes two bugs:
Language parameters invalidation:
1. Access the webclient in a specific language
2. Modify the language parameters (e.g. thousands separator)
3. Refresh the page
--> webclient is still using old language parameters (from cache)
No translation flag after installing a language:
1. Load a database in English in mono-language
2. Load a second language
3. Access a record with a translated field
--> translation button not present on translated field (multi_lang is still
false in cache value)
To fix it, this commit adds all the information that are returns by the
/web/webclient/translations call to make sure the hash represent the reality
