[PATCHv4 2/4] `remember-append-to-file' appending to buffer bug fix

[Michal Nazarewicz <mina86@mina86.com>]

* remember.el (remember-append-to-file): Function used
`find-buffer-visiting' to check whether a file visiting
`remember-data-file` existed but then `get-buffer-visiting' to
retrieve it.  However, the latter requires exact string match so
it could return nil even though the former found a buffer.
Storing result of the `find-buffer-visiting' fixes the issue (and
saves one lookup).
