ARROW-3543: [R] Better support for timestamp format and time zones in R Most of this patch is test refactoring in test-Array.R, with the purpose of making sure that our R <--> Arrow roundtrips are faithful. In the process this uncovered a few issues we weren't handling correctly, and in fixing the timezone handling for timestamps, I realized that this longstanding bug might also be fixed. https://github.com/apache/arrow/commit/507762fa51d17e61f08d36d3626ab8b8df716198 is the commit with the bugfix. Closes #6488 from nealrichardson/fixing-stuff and squashes the following commits: d261e0f5e <Neal Richardson> Try to stabilize no-TZ timestamp test ffc58d2e2 <Neal Richardson> Try for better printing to debug test failure 8604a70bb <Neal Richardson> PR comments 744851c42 <Neal Richardson> Update more test expectations d1594edd2 <Neal Richardson> Test confirming that the timezone roundtrip fixes ARROW-3543 f27395756 <Neal Richardson> Un-hardcode GMT as timezone 01121203d <Neal Richardson> Add is.na around Array__Mask.
