[Core] Don't swallow parse errors on the CLI (#2632)

With v7.6.0 in 3bc80b9 before all and after
all hooks were introduced. This moved parsing of features into the execution
context. This resulted in any parse errors being swallowed with the assumption
that they would have been captured by the execution context already.

Fixes: #2631
