fix(kernel/default_converter): broken optimization
...
we must also check the universe levels when applying the optimization for
constraints of the form:
f.{l_1 ... l_k} a_1 ... a_n =?= f.{l_1' ... l_k'} b_1 ... b_n
The optimization tries to avoid unfolding f if we can establish that
a_i is definitionally equal to b_i for each i in [1, n]

fix(library/tactic): we must unfold untrusted macros when type checking intermediate results
...
Example: before this commit, the file librata/data/list/perm.lean would
not type check if the option -t 0 (trust level zero) was provided.
Reason: the intermediate term contained a macro, and macros are not
allowed at trust level zero.
