A previous change intended to prevent temporary directories created as
an implementation detail of mounting volumes on kubernetes pods from
being used as a source for property files had a side-effect of also
preventing other types of hidden directories from being recognized. This
commit narrows the criteria for considering a directory as hidden,
using the kubernetes `..` prefix convention instead of the Unix `.`
prefix.

Previously, when an embedded test database was being auto-configured
any schema username and password specified by the user would result
in a separate embedded test database being created to load the schema.
This then left the actual test database without the schema causing
test failures.

This commit updates the test database auto-configuration to set the
schema username to an empty string in a property source that's added
first to the environment's property sources. This causes any schema
username configured by the user to be ignored, preventing the creation
of a separate database for schema.sql processing.
