vis:pipe(): don't segfault if vis->win isn't present
When `file` was made optional the variable was changed to be initialized
by `vis->win->file` instead of a known safe file pointer. If `vis:pipe()`
is called based on the event `FILE_OPEN` the `file` parameter can be
valid even when `vis->win` is not yet present. Assuming `file` was
provided this would be handled later on if vis didn't segfault. By
initializing to NULL when `vis->win` isn't present `file` is given
a chance be handled later. In the case where `file` wasn't given and
`vis->win` is missing an error is thrown and `vis:pipe()` exits.
fixes #1107 - Lua API: vis:pipe() causes a segfault when called before
a window is open
