fix: preserve info flag in plugin reports with --global

The argument-handling block in each plugin's report command overwrote APP with --global before checking whether $1 actually held an info flag, so `dokku <plugin>:report --global --<plugin>-foo` always emitted the full report instead of the requested value. Reorder the conditionals across the sixteen plugins that share the pattern so the info-flag check runs first, and add a regression bats case for each one.
