auto retry timing bug

[jmarsico]

Not sure if you're interested in stable branch issues. I haven't tried this on master yet:

after the first auto retry, getTimeTillNextAutoRetry() returns the max uint64 minus (what i assume is) elapsed time. I tried looking through the relevant code, but can't figure out what's going wrong. getTimeTillNextAutoRetry() works for the first reconnect attempt, after that it jumps to the large number.

I see this in my code and in the example.
