#2 Bug#1501440 fix + random uniqueID generation

[Anonymous]

I fixed #1501440 bug with changing Set to ArrayList in
getTerminals() and terminalDataArray() methods. Also,
response.getUniqueId() was returning null, so I add
generating Random ID's.

The value of uniqueId is from Asterisk. If it is not
set we have to investigate that situation. Either
fix Asterisk or cope with the null.

I don't see a semantic change of the things around
terminalDataArray. An ArrayList IS A Set, we don't
need to copy that.
