Suggest only if the callee matches the trigger (#247)

The issue here is a call to
    hvcat(rows::Tuple{Vararg{Int}}, xs::_DenseConcatGroup...) = Base.typed_hvcat(promote_eltype(xs...), rows, xs...)
which has a couple of `Core._apply_iterate` and the matching fails
when it doesn't match the trigger `promote_eltype`.
I tried to come up with a MWE but failed.

Fixes #244
