include model name in Media asserts

[Mathadon]

The BaseProperties temperature check does not report in what model the temperature limits are exceeded. This can be improved for easier debugging.

@Mathadon : While testing your pull request, I get

In MixingVolumeHeatConduction.vol.dynBal.medium: Temperature T is not in the allowed range
200.0 K <= (T =423.15 K) <= 423.15 K
required from medium model "Air".
  Failed condition: vol.dynBal.medium.T >= 200.0 and vol.dynBal.medium.T <= 423.15

What does getInstanceName() add, as the message already said vol.dynBal.medium.T.

Also, I would prefer the following error message that directly tells the user which limit is exceeded, and does so in degC which are more intuitive:

Temperature T exceeded its maximum allowed value of 150 degC (423.15 Kelvin)
as required from medium model "Air".
  Failed condition: vol.dynBal.medium.T <= 423.15

and similarly

Temperature T exceeded its minimum allowed value of -73.15 degC (200 Kelvin)
as required from medium model "Air".
  Failed condition: vol.dynBal.medium.T >= 200.0

I implemented these message on branch issue1045_mediaAssert_separateMinMax and made a new pull request.

The two tests are not more expensive as the and also requires monitoring two zero crossing functions.

JModelica doesn't add the variable name, so then it does make a difference.
