This simplifies the code since one no longer needs to think about
whether '.guix-channel' was present.
* guix/channels.scm (read-channel-metadata): Always pass a string as the
first argument to 'channel-metadata'.
(read-channel-metadata-from-source): Always return a <channel-metadata>
record.
(channel-instance-dependencies): Remove now unneeded 'match'.
(standard-module-derivation): Assume DIRECTORY is never #f and contains
a leading slash.
* tests/channels.scm (channel-metadata-directory)
(channel-metadata-dependencies): New procedures.
("channel-instance-metadata returns #f if .guix-channel does not
exist"): Remove.
("channel-instance-metadata returns default if .guix-channel does not
exist"): New test.
(make-instance): Use 'write' instead of 'display' when creating
'.guix-channel'.
(instance--no-deps): Remove dependencies.
(instance--sub-directory): New variable.
("channel-instance-metadata and default dependencies")
("channel-instance-metadata and directory"): New tests.
("latest-channel-instances excludes duplicate channel dependencies"):
Expect 'channel-commit' to return a string and adjust accordingly.
