When trying to use an unexisting list function, to alter a view, the error is
not a missing document error, but an obscure "TypeError" saying that "point is
undefined" because of the way the javascript code in couchdb server tries to
find the list function.

This commit adds a catch for that error and raises the proper exception in the
soledad couch module.

Using real uuid to separate Locks on each test allow them to
be run in parallel. Using real uuid also allows parallel syncs.
This is being done to allow test suite to run in parallel on future.

Now the CouchDB based tests will try 3 times before give up due to
timeout or some temporary error. The stop function will also execute
properly even if the process wasn't created, leaving no lost files or
folders behind.

As described in #4691, sometimes couch just hangs and all testing
freezes. This is due to no output from couch (sometimes meaning that an
error on boot wasn't logged). This adds a timeout and checks for it
while booting for tests. Closes #4691

CouchServerState does not use two extra parameters anymore. Tests are
now reflecting this change. Relate to #6833

The .ini used before was very old and did not contain all the config
values that couch needs. Using -n resets the configuration file chain,
making it use what is provided without including the system defaults
needed. To make it work with all versions the util will now copy
default.ini to temp dir and use it as additional config, overwriting
only what is needed with couchdb.ini.template provided.

This commit removes some leftover code from a time when Soledad Server used to
check for permissions on certain databases when starting (i.e. shared and
tokens databases). This was later removed as correct permissions enforcement
was relayed to tapicero.

Closes: #6833.
