make clickSelector a retry in case it fails the first time

[stacey-gammon]

Another attempt to fix my latest encounter with #12014

Based on the output I saw:

And the screenshot:

It looks like the first attempt to clickVisualize failed with element not visible. The visualize link is visible but I'm hoping wrapping the clickSelector in a retry might avoid this in the future. Also spitting out some debug statements since there wasn't much to go on.

passed once,

Jenkins, test this.
