Leonardo de Moura d88a6f663e fix(frontends/lean/elaborator): implicit arguments after auto_param arguments

Function applications `(f ...)` were not being elaborated correctly when
`f` has implicit parameters occurring after auto_params.
The new test exposes the problem.

This bug was found when developing the red black tree module.

This commit also fixes the following bugs:

- Invoke type class resolution again after tactic execution at
  synthesize method. Reason: metavariables occurring in type
  class instances may have been synthesized by tactics.

- mctx.assign optimization at invoke_tactic was incorrect
  when the metavariable was assigned by typing rules.
