patch 8.2.1479: Vim9: error for list index uses wrong line number

Browse Source 
Problem:    Vim9: error for list index uses wrong line number.
Solution:   Set source line number. (closes #6724)  Add a way to assert the
            line number of the error with assert_fails().

Run {cmd} and add an error message to |v:errors| if it does
NOT produce an error or when {error} is not found in the
error message. Also see |assert-return|.

If {msg} is empty then it is not used. Do this to get the
default message when passing the {lnum} argument.
When {lnum} is present and not negative, and the {error}
argument is present and matches, then this is compared with
the line number at which the error was reported. That can be
the line number in a function or in a script.
Note that beeping is not considered an error, and some failing
commands only beep. Use |assert_beeps()| for those.
Can also be used as a |method|: >

assert_false({actual} [, {msg}]) *assert_false()*
assert_false({actual} [, {msg}]) *assert_false()*
When {actual} is not false an error message is added to
|v:errors|, like with |assert_equal()|.
Also see |assert-return|.
