Incorrect Solution.ID for YAML generated objects

[ischoegl]

Cantera version

2.5.0a3

Python version

3.6

Expected Behavior

gas.ID should provide the ID of the phase, with the default being taken from the input file. I.e.

gas = ct.Solution('nDodecane_Reitz.yaml')
print(gas.ID)

should be nDodecane_RK. I.e. the result should be identical to the one obtained if one were to import the CTI file. Explicitly specifying the phase (i.e. nDodecane_RK or nDodecane_IG) will not change the behavior.

Actual Behavior

gas = ct.Solution('nDodecane_Reitz.yaml')
print(gas.ID)

yields <phase>, regardless of the mechanism that is imported.

Steps to reproduce

See above.
