Need to skip trailing newline/whitespace on the expression: I tried
updating the test to add further text:
```java
protected Entity entityWithMultilineTemplatedString() throws Exception {
return setupAndCheckTestEntityInBasicYamlWith(
" id: x",
" brooklyn.config:",
" test.sourceName: hello world",
" test.confName: |",
" $brooklyn:template",
" ${config['test.sourceName']}",
" test.other: something else");
}
```
and it breaks with
```
java.lang.AssertionError: expected [hello world] but found [hello world
]
```
