tests: introduce REUSE_TEST_DB as an alternative to TEST_DB

With TEST_DB, the specified database would be dropped (if existing) and created
from scratch. That would fail if the user only had been granted access to that
database without general database creation permissions.

With REUSE_TEST_DB, the database must exist, and the tables in the existing
database will be deleted before creating the new ones.

This is for example useful for testing on PostgreSQL without full database
privileges. (With MariaDB/MySQL, it is possible to grant create permissions to
a database before it exists, so it is easier to use TEST_DB.)

 Tests can be run on PostgreSQL like::
     sudo -u postgres createuser 'kallithea-test' --pwprompt  # password password
     sudo -u postgres createdb 'kallithea-test' --owner 'kallithea-test'
     REUSE_TEST_DB='postgresql://kallithea-test:password@localhost/kallithea-test' py.test
 Tests can be run on MariaDB/MySQL like::
     echo "GRANT ALL PRIVILEGES ON \`kallithea-test\`.* TO 'kallithea-test'@'localhost' IDENTIFIED BY 'password'" | sudo -u mysql mysql
     TEST_DB='mysql://kallithea-test:password@localhost/kallithea-test?charset=utf8' py.test
 You can also use ``tox`` to run the tests with all supported Python versions.
 When running tests, Kallithea generates a `test.ini` based on template values
