Originally, this diff was just making sure that the `dispatch` didn't occur before `REHYDRATE`. But when testing that change I found that calling `dispatch` from a reducer triggered an error. More context in [this comment](https://phab.comm.dev/D5672#169056), but this diff is now just removing the `dispatch`, with the expectation that the error-handling functionality here will be improved following the work in [ENG-1974](https://linear.app/comm/issue/ENG-1974/analysis-of-errors-in-sqlitequeryexecutor).
