`mysql-simple-0.4.7` incompatible with resolver

while I was hacking #1452 I ran into trouble with stack and the declared version of mysql-simple. bumping the version to mysql-simple-0.4.9 (after the date-time-compat api changed) worked for me, but I am not a stack-knower, so please take this with a grain of salt 😅

Start by reproducing the Stack build failure for mysql-simple 0.4.7 and inspect the dependency declaration that selects this version. Confirm that the selected mysql-simple version compiles with the current Data.Time.Format API and that the affected Stack build completes successfully.
