IDML Merge not working

Created by: lavbox

When I merge the IDML document using Tikal -m command, the resultant document has additional new translation units.

Steps to repro:

Extract XLIFF file using -x command with given filter configuration.
```
 java -jar tikal.jar -x file.idml -fc okf_idml@test.fprm
```

Merge the generated XLIFF using -m command

 java -jar tikal.jar -m file.idml.xlf -fc okf_idml@test.fprm

Extract XLIFF file from the output generated in step 2.

 java -jar tikal.jar -x file.out.idml -fc okf_idml@test.fprm

Actual Result:

When you compare XLIFF generated in step 1 and step 3, there are few new translation units.

Expectation:

Translation units in XLIFF files in step 1 and step 3 should be identical.
