warning on empty message formatted by glue

[daroczig]

Hi,

While preparing a CRAN update and running the reverse dependency checks for logger, I've run into an issue with https://github.com/atalv/azlogr/blob/main/tests/testthat/test-logger_level.R#L161 -- daroczig/logger#147 introduced throwing a warning when formatter_glue return no message to note to the user that something is off.

Your above test line explicitly expects no warnings, so the above PR could not go into main, and we had to revert the PR.

Would you feel comfortable dropping that test line and accepting a warning from formatter_glue when it renders no message? If that's an unwanted behaviour, could you please comment on daroczig/logger#130 so that we can discuss what's a good solution for your use-cases?

Thanks,
Gergely (maintainer of logger)

Makes sense. I made relevant changes and submitted to CRAN
