fix: limit-access-to-actor functionality

[mxschmitt]

This was a regression introduced in #64 which broke the limit-access-to-actor functionality.

The order of the input parameters seems important, since first the parameters from tmate come and then from tmux.

Fixes #65

tested with:

name: CI
on: [push]
jobs:
  test:
    runs-on: ubuntu-latest
    name: test
    steps:
    - uses: actions/checkout@v2
    - name: Setup tmate session
      uses: mxschmitt/action-tmate@bugfix/limit-access-to-actor
      with:
        limit-access-to-actor: true

Ooops, sorry for the breakage!
