Ungrouping after rowwise grouping removes tbl class.

[felasa]

May be intended but found it annoying:

If you ungroup a tbl after doing rowwise() grouping, it removes the tbl (and tbl_df) class from the object and reverts to a vanilla data.frame.

Examples

iris %>% tbl_df %>% rowwise %>% ungroup %>% class
[1] "data.frame"

iris %>% tbl_df %>% group_by(Species) %>% ungroup %>% class
[1] "tbl_df"     "tbl"        "data.frame"

iris %>% tbl_df %>% ungroup %>% class
[1] "tbl_df"     "tbl"        "data.frame"

Duplicate of #936 I guess.
