Parsing of table literal as an argument is inconsistent

Describe the bug

It appears that parsing of the header form of table literals is incorrect for at least the table argument of the join command. Perhaps this happens for other commands, too?

How to reproduce

Run this script:

use std assert

# start figuring out the relation between islands in Riven :grin:

let list_of_records = [{"island name": boiler}]
let table = [["island name"]; [boiler]]

assert ($list_of_records == $table)
assert (($list_of_records | join $list_of_records "island name") == $table)

assert (($table | join $list_of_records "island name") == $table)
assert (($table | join ([{"island name": boiler}]) "island name") == $table)
assert (($table | join [{"island name": boiler}] "island name") == $table)

assert (($table | join $table "island name") == $table)
assert (($table | join ([["island name"]; [boiler]]) "island name") == $table)
assert (($table | join [["island name"]; [boiler]] "island name") == $table) # fails :'(

Expected behavior

The final line:

assert (($table | join [["island name"]; [boiler]] "island name") == $table) # fails :'(

…should not fail its assert call.

No response

Start by running the reproduction script from the issue and compare the passing and failing join invocations. Trace how the Nushell parser handles header-form table literals when they are passed directly as command arguments. Done means the final assertion passes consistently without changing the equivalent parenthesized cases.
