fix: mv id() to getObjectID().index because id() returns ObjectID, no…

…t uint_t, in podio v0.17.1 (#1106)

### Briefly, what does this PR introduce?
This adds forward compatibility with podio v0.17.1. See
AIDASoft/podio#493

### What kind of change does this PR introduce?
- [x] Bug fix (issue: compilation falures with podio 0.17.1)
- [ ] New feature (issue #__)
- [ ] Documentation update
- [ ] Other: __

### Please check if this PR fulfills the following:
- [ ] Tests for the changes have been added
- [ ] Documentation has been added / updated
- [ ] Changes have been communicated to collaborators

### Does this PR introduce breaking changes? What changes might users
need to make to their code?
No.

### Does this PR change default behavior?
No. The modified algorithms are not relying on the most significant bits
in the previous ObjectID uint_t that encode the collectionID.
