fix: revert reset of ticker

[powersj]

Revert the previous PR. In scenarios where inputs fill the batch size
before the flush interval is hit batches are continuously ready for writing.
When batches are called it resets the flush interval. This results in the
flush interval event getting starved and never called.

To the end users this looks like the Telegraf buffer always increasing.
This is because the full write is never called, only batch write. The
only way at present to call write is to kill telegraf.

Resolves: #9799, #9531, #9726

Required for all PRs:

• Updated associated README.md.
• Wrote appropriate unit tests.
• Pull request title or commits are in conventional commit format (e.g. feat: or fix:)

Hi @powersj does this also resolve #9531 and #9726? (If so, we should link them as well)
