Explicitly declare copy assignment for bqueue

[Dr15Jones]

PR description:

The clang compiler was warning about classes which had bqueue objects as members were unable to implement copy assignment operators because bqueue had not explicitly declared one.

PR validation:

Compiling under clang no longer gives a warning.
The extension of the unit test to test copy assignment passes.
