revsLimit and adapter variables switched in __computeDb

[jarrodek]

Description

In the AppPouchDBDatabaseBehavior function __computeDb has switched arduments. According to db attribute definition this is computed by __computeDb(dbName, adapter, revsLimit) however, actual function body is __computeDb: function(name, revsLimit, adapter).
It causes error when trying to put anything to the data store:

Uncaught TypeError: Cannot read property '2' of undefined

This error is caused because of the switch. At this point PouchDB is expecting different parameter. After I switch back this parameters in by bower_components folder my test cases started working.
