Minor commits triggers major release of pre-release

[trygve-lie]

Current behavior

We have a setup for pre-releases following this workflow. Our only difference is that we have set a next branch to be pre-release.

Our first merge of a PR to the next branch had a breaking change footer. This was detected as a major release and did trigger a new major release (3.0.0-next.1) as expected.

Then we merged a PR marked as feat containing no breaking changes footer into the next branch.

Semantic release detected this as a minor release but did a new major release (4.0.0-next.1):

Expected behavior

We expected that the last PR flagged as a minor to be released as a minor and not a major. In other words; we expected a 3.0.0-next.2 and not a 4.0.0-next.1 release.
