function i18n_string_install_update_context in Internationalization 7

Update context for strings.

As some string locations depend on configurable values, the field needs sometimes to be updated without losing existing translations. I.e:

• profile fields indexed by field name.
• content types indexted by low level content type name.

Example: 'profile:field:oldfield:*' -> 'profile:field:newfield:*'
