Similar strings and missing plural for users page

[pavelevap]

• There are 3 similar strings, we can make only one. There is no need for other strings for Users, because there is only one string for Posts, Plugins, etc.

• We have plural for deleting users, there should be also plural for removing users.

See attached patch.
