[vector] RFR:8244269: vector api tests crashed with "assert(is_location()) failed: must be"

[Paul Sandoz]

Looks good.

Would you mind wrapping lines longer that 120 characters? Otherwise its hard to read and review.
Specifically, in the argument accepting iotaShuffle method e.g. start the lambda expression on a new line.
No need for another review.
