Execution ID (Un-)Prefixing does not work with both syntax options

[u3r]

While trying to override an execution (from a non-tiled parent) I discoverd that dependant on versions of the tiles-plugin only one of the syntax options work.

Version 2.12 (both for tile building and execution)
only

<configuration tiles-keep-id="true" />

works.

Version 2.14 (both for tile building and execution)
only

<configuration>
   <tiles-keep-id>true</tiles-keep-id>
</configuration> 

works.

Inclusion of the tile was within a profile.
