libclementine-common: Use positive numbers for worker ids.

Browse Source 
QRandomGenerator::generate() returns an unbounded int32, while the legacy
qrand method always returned a positive number. When generating a tag
reader ID with QRandomGenerator, cast the random value to an unsigned so
that it is formatted as a positive number in the name.

Note that most usages of QRandomGenrator in the codebase use bounded()
instead of generate(), and should work as expected.
