Remove unused internal method parameter

The getSSLSocketFactory(...) method was being passed a boolean
value for whether or not to trust all certificates. That value
is not being used as the method instead goes directly to the
connection options via jdbcUrl.getOptions(). This patch removes
the unused parameter from the method and single invocation.
