This does the same for the other specs, as previously done to the
page.js spec in 058d5b7cd8.
* rollkback: From 6 api logins to 4 api logins.
Before (2x3): admin for edit, admin for createaccount, vandal for edit.
After (2x2): admin for edit + createaccount, vandal for edit.
* recentchanges spec: No difference, but updated pattern for consistency
so that if it is extended in the future, it will be natural to re-use
the bot object instead of creating a new one.
* watchlist spec: From 3 api logins to 1 api login.
Before: admin for createaccount, admin for edit, admin for edit.
After: admin (re-used)
* user spec: From 2 to 1 api login.
Also:
* Remove the now-unused Api.edit() and Api.delete() anti-pattern
methods, as these are nothing but one-line shortcuts to the
already one-line invocation of bot.edit() and bot.delete(),
except that they bypassed the current bot object, causing
inefficient repeat logins in way that was non-obvious.
Migration is simple and won't be required until other repos
upgrade to the next wdio-mediawiki version (not yet released).
* Make 'bot' a mandatory parameter for the createAccount, block,
and unblock convenience wrapper methods.
* Move the vandalizePage() method from HistoryPage to rollback spec,
as it had no connection with that page object or the action=history
interface, and document why it can't (yet) re-use its bot object.
