[IMP] payment_sips: testing values

Prior to this revision, setting the provider to the 'test' mode caused
hardcoded values for merchantId, secret and keyVersion to be used
without any possibility to override them.

While somewhat useful, it was quite limiting since it used the 'simu'
environment of Atos Wordline, preventing you from testing any other
platform and from using the 'test' environment for Atos.

This revision removes these hardcoded values, which gives more
flexibility as far as testing goes at the cost of a bit more setup
(since you might need to change some values manually, notably the
keyVersion).
