Update gamTest (and gamTestSeason) when gamTable = FALSE

[jharcum]

Describe the solution you'd like
When baytrends is run in a Rmd script and gamTable = FALSE, figures are placed back to back and the formatting (at least to Word documents) is not clean. So probably need to adjust gamTest to include printing a blank line (i.e., print(" ")) to clean up Rmd script output.
