BEAUTi: missing Tree prior parameters when switching between templates

[jugne]

When switching between prior templates of BDSky, Tree parameters are not updated correctly.

To reproduce with version 2.7.7:

• first select Birth Death Skyline Multi Rho template and expand Tree panel.
• then select Birth Death Skyline Contemporary template, notice that Rho Sampling Times in Tree panel disappear (this is correct behaviour)
• go back to the Birth Death Skyline Multi Rho template. The Rho Sampling Times parameter in Tree panel does not appear again, which it should.

~Coalescent templates seem to handle switching correctly, maybe that helps to narrow it down.~ Coalescent handles it because the different parameterisations are in separate classes.

This is due to different parameters in suppressInputs for different templates. Could be fixed if using ParameterizedBirthDeathSkylineModel instead of BirthDeathSkylineModel.

Possibly there is another workaround..
