Cannot run @report_call on Julia 1.8-beta1

[jakobnissen]

This is using Julia 1.8.0-beta1, in an empty environment with JET 0.5.7:

The reproducer (same as #321 ) and top of stacktrace

julia> using JET

julia> function f()
           v = map((2,)) do i
              isodd(i) ? i : ""
           end
           convert(Tuple{Int}, v)
       end
f (generic function with 1 method)

I can also reproduce it with

using Random

julia> @report_call Random.seed!(42)

Or with report_package
