Record log does not list correct starting before elements

[remcowesterhoud]

Describe the bug

In the PROC_INST_CREATION record we will log the elements which the process started at. If a process starts at 2 different element this record will log the same id twice, instead of logging both ids.

To Reproduce

Create a process instance. Start it at 2 different elements. When you look at the creation record it will say it started at the same element twice.

Expected behavior

The records logs shows the correct elements that were started at.

Log/Stacktrace

C PROC_INST_CREATION CREATE         - #006->  -1   -1 - new <process "process_id_27"> (starting before elements: fork_id_18, fork_id_18)  with variables: {boundary_timer_id_25=PT8760H, boundary_timer_id_23=PT8760H, correlationKey=default_correlation_key}
...
C PROC_INST          ACTIVATE       - #012->#006 K008 - RECEIVE_TASK "id_16" in <process "process_id_27"[K004]>
C PROC_INST          ACTIVATE       - #013->#006 K009 - PARALLEL_GATEWAY "fork_id_18" in <process "process_id_27"[K004]>
E PROC_INST_CREATION CREATED        - #014->#006 K010 - new <process "process_id_27"> (starting before elements: fork_id_18, fork_id_18)  with variables: {boundary_timer_id_25=PT8760H, boundary_timer_id_23=PT8760H, correlationKey=default_correlation_key}

This shows we started at fork_id_18 twice, but when looking at the activate commands we can see that we actually started at fork_id_18 and id_16
