gnc-fq-dump doesn't work for most sources

[Brian M. Sutin]

I am unable to get gnc-fq-dump to work on almost everything.  I am running
v1.45 on Ubuntu.  I did get a hit off of TIAA-CREF, so it works in general.

$ gnc-fq-dump -v vanguard VTSAX
    No results found for stock VTSAX.

$ gnc-fq-dump -v nasdaq ibm
    No results found for stock ibm.

$ gnc-fq-dump -v nyse ATGE
    No results found for stock ATGE.

$ gnc-fq-dump -v alphavantage ibm
    Finance::Quote fields Gnucash uses:
	symbol: ibm (deduced)        <=== required
	  date: ** missing **        <=== recommended

I *did* add the alphavantage key to /etc/gnucash/environment:

    #<...snip...>
    # LANG=nl_BE
    # LANGUAGE={LANG}
    # added for quote retrieval
