`Automa.execute` gives wrong result in some case

[Kolaru]

When usinge for example RegExp.rep I get re.rep("a") to parse "aYa" through Automa.execute:

using Automa
import Automa.RegExp: @re_str
const re = Automa.RegExp

a = re"a"
a.actions[:exit] = [:a]
withrep = Automa.compile(re.rep(a))
Automa.execute(withrep, "aYa")  # return (0, [:a, :a])

Actually generating the machine code and executing correctly fails to parse "aYa". I believe the following should do the exact same thing as Automa.execute:

context = Automa.CodeGenContext()
@eval function test_func(data)
    $(Automa.generate_init_code(context, test))
    p_end = p_eof = lastindex(data)
    as = []
    emit() = push!(as, :a)
    $(Automa.generate_exec_code(context, test, Dict(:a => :(emit()))))
    return cs, as
end

test_func("aYa")  # (-2, Any[])
test_func("aa")  # (0, Any["a", "a"])

I'm using Automa 0.8.2.

Fixed in #79.
The fix is a single line, so you can add it to your own code if you want.
