Tibble is printed in some modules

Run:
```
example(tm_t_pp_laboratory, package = 'teal.modules.clinical')
# or: example(tm_t_pp_prior_medication, package = 'teal.modules.clinical')
shinyApp(app$ui, app$server)
```
and add a first, default view to a reporter. The table printed in output is a tibble, which adds some unnecessary features and more technical formatting. Maybe add:
```
labor_table_html_dt %>% as.data.frame()
```
(or use rtables)


Reproduce the issue with the tm_t_pp_laboratory or tm_t_pp_prior_medication examples and the shown shinyApp commands. Trace the first default reporter view and inspect labor_table_html_dt; done means the displayed table no longer has tibble-specific formatting or extra technical features.
