ergm formula error on GOF plot when multiple models are saved

[martinamorris]

1. fitting edges+nodecov("wealth") produces this GOF plot page, no error:

2. fitting sequentially, first edges, saving the model, then +nodecov("wealth") and saving the model, produces this GOF plot page with error

to reproduce:

library(statnetWeb)
run_sw()

and interactively:

1. on Data tab select flomarriage network
2. on Fit Model tab:
   • Add Term(s) edges
   • Fit Model
   • Save Current Model (will be 1/5)
   • Add Term(s) nodecov("wealth")
   • Save Current Model (will be 2/5)
     3. on Goodness of Fit tab
   • error will be displayed in ergm formula on top of page

Here is what shows in the Rstudio console window:

Warning in if (!is.na(attribValue)) { :
  the condition has length > 1 and only the first element will be used

Not happening in master. Probably fixed last year in 2085fd8f1a5517fbd55fd128baa6796445b2c725.
