No block should depend with `mustDeps` on i-jquery

i-jquery is just a template - so there is no reason to specify it
in `mustDeps`, jQuery code itself won't be included before the said
block in built file.
Such dependences result in `mustDeps` cycle that can not be resolved,
so, depending on a deps tech we either get an error, or some build file
that can be build correctly or not depending on a moon phase and luck
stat of the programmer.
