Github Actions: 157-date-format test failure

[MadhulikaTanuboddi]

This test has been consistently failing on Mac: 4.0 and Ubuntu-18: 4.0 runs. Remaining 10 runs (Mac, Windows, Ubuntu with other versions of R) looks good with this test.

I am able to repro this locally on Mac with 4.0.

Steps:

1. Install the latest of shinycoreci -> remotes::install_github("rstudio/shinycoreci")
2. Set your RStudio IDE working directory to https://github.com/rstudio/shinycoreci-apps/tree/master/apps
3. Run the app 157-date-format using shiny::runApp(apps/157-date-format) or shinyjster::run_jster('apps/157-date-format')

Expected: App should show 14 warnings Actual: On Mac, the shinyjster test fails showing only 13 warnings. The test works on Windows.

> shinyjster::run_jster('apps/157-date-format')

Note: Barret helped me with some debugging. It looks like the warming message catchWarning(dateInput, "x2", "Mis-specifiedmin", min = ""), is not printed. Not sure if this makes sense -> when I added a empty string to min i.e min=" ", the warning is printed

Could this be due to https://github.com/rstudio/shiny/issues/2591?

I think this should be fixed now (please reopen if not)

Verifed and looks good. Thank you @cpsievert
