ejabberd: tests: functional: Fixes for no implicit waiting

- When 'relogin' hit is seen after page load, reload the page instead of trying
to login as it does not always succeed.

- Wait after the page load until the connection with jabber server has been
checked.

- Wait until the roster appears after login.

- Wait until contact appears after contact is added.

- Wait for popups and dialogs when deleting the contact.

- Wait for contact to appear when checking for contact. Don't reload on every
check.
