Ensure that Dirichlet-multinomial parameters are not turned on

```
#_age_info
#_mintailcomp	addtocomp	combine_M_F	CompressBins	CompError	ParmSelect	minsamplesize
-1	0.001	0	0	1	1	0.001	#_Fishery        
0	0.001	0	0	1	2	0.001	#_Acoustic_Survey
-1	0.001	0	0	0	0	0.001	#_Age1_Survey
```
No composition data, so we just want multinomial error for the age-1 survey.
