How can library open the database if it doesn't read the config file
-- the config file defines where database is located =D

If the library can somehow guess the location of the database without
reading the config file ;D I think dumping -- editing -- restoring
the database is tolerable solution -- provided it is clearly documented
for people like me who wants to edit configuration files w/ text editor(*),
for forgets these instructions easily. If, in the future, we still have
configuration file(+), notmuch could also write such instructions to
the config file.

(*) like someone may know I'm not too fond of editing configuration files
    when there are alternatives available (like in this case) -- however
    is someone else(tm) takes the time to create this solution and it uses
    configuration files, I'll use it...

(+) if we dropped the configuration file, then notmuch, and library could
    open database from ~/mail/notmuch/ by default, or from location pointed
    by e.g. NOTMUCH_DATABASE_DIR -- as an additional benefit(?) notmuch
    would pollute user's $HOME by one file less -- the `.notmuch-config`.
