Patches for dplyr type conversions

[dsweber2]

Various functions will convert epi_df's to tibbles. This is to catalog which of those have been fixed/don't need to be fixed

• arrange
• complete
• distinct
• filter
• slice*
• glimpse (doesn't make sense)
• mutate
• pull (doesn't make sense)
• relocate (some design choices to be made)
• rename
• select (PR patch: get select working with grouping #390)
• count, tally, (may not make sense)
• add_count, add_tally
• summarize (doesn't make sense)
• n, cur_group, cur_group_id etc doesn't really make sense
• bind_cols (also doesn't work for ungrouped)
• bind_rows
• intersect, union etc
• inner_join

we also need something simliar for epi_archive's. filter for example doesn't work.
