Fix regressions resulting from cascade removal from relationships in TaxEditor

Description

See #7392

At some places transient object exceptions are thrown.

Known issues:

new misapplied name in name editor
creating a new hybrid formula, e.g. Abies alba x Pinus beta with "new taxon"
also when adding it e.g. as a synonym in the name editor an exception is thrown - but an NPE during caching, not a transient object exception (see comment 1), however it is a regression to 4.14.1 and therefore maybe related to the cascade issue
