installer: Makes sure the installer proceeds after hitting "Edit".
Fixes <https://bugs.gnu.org/39199>. Reported by Jonathan Brielmaier <jonathan.brielmaier@web.de>. * gnu/installer/newt/page.scm (run-file-textbox-page): Move 'loop' to the beginning of the body. Do not call 'loop' from the 'dynamic-wind' exit handler as we would not return the value of the second call to 'loop'.
