mobile.special.watchlist.scripts makes use of the mobile.watchlist module. Nothing else makes use of this module, thus it makes sense to merge it into the mobile.special.watchlist.scripts module

Note: mobile.watchlist has dependencies on mobile.startup and mobile.scrollEndEventEmitter. These modules will be retained during this change and these dependencies copied to the merged entry point to keep this tightly scoped. Given a usage in category overlay, it is not trivial to merge in mobile.scrollEndEventEmitter.

Acceptance criteria

• The code in mobile.special.watchlist.scripts is built via webpack
• The code in mobile.startup has not grown in any substantial way. Consider introducing a new module mobile.special.scripts (to mirror mobile.special.styles) modules if this becomes a problem that can be shared across all special pages.
• The module mobile.watchlist has been removed (no need to worry about caching!).
• The tests in mobile.watchlist are run inside webpack
• mobile.special.watchlist.scripts has dependencies mobile.scrollEndEventEmitter and mobile.startup
