In commit fec441ec17 (Teach CROSSCOMPILING_EMULATOR to support
arguments, 2019-05-30, v3.15.0-rc1~6^2) the new member
`cmCustomCommandGenerator::EmulatorsWithArguments` was not initialized
to the proper size. Fix this and add a test case covering the crash
that could occur with multiple commands where an emulator appears only
in a later command.
Fixes: #19500
