Message Store

**Citrus Version**
Citrus Tests 2.7.2

**Expected behavior**
when receiving message and declaring name, message should be accessible from message store

**Actual behavior**
echo works just fine using declared name, but message isnt storing in message store, or accessible. Shows as empty

**Test case sample**
> Please, share the test case (as small as possible) which shows the issue
When using test injected Citrus resource test context, and trying to call on messageStore().getMessage().getPayload(), test throws null pointer because it shows there are 0 messages in message store.
