[axs03 branch, test_axs.sh]: Name of results in axs command doesn't work.

[maria-18-git]

The following commands don't work in test_axs.sh:
1 - axs03 d: bypath dad , dig d.multisub2.1 --epsilon=3333
2 - axs03 d: bypath dad , dig d.multisub2.1 --epsilon=3333 , , get d , dig d.multisub2.1 --epsilon=444

Results: KeyError: 'd'

1. Run

axs03 fresh_entry , plant alpha 10 beta 20 gamma 30 multisub --:="AS^IS:^^:substitute:#{alpha}#, #{beta}# and #{gamma}#" , save grandma
axs03 fresh_entry , plant beta 200 gamma 300 _parent_entries --,:=AS^IS:^:bypath:grandma , save mum
assert 'axs03 bypath mum , substitute "#{alpha}# and #{beta}#"' '10 and 200'
assert 'axs03 bypath mum , get multisub --beta=2000' '10, 2000 and 300'
axs03 fresh_entry , plant gamma 31 delta 41 epsilon 51 zeta 60 multisub2 --,:="AS^IS:^^:substitute:#{gamma}#-#{delta}#,AS^IS:^^:substitute:#{epsilon}#-#{zeta}#" , save granddad
axs03 fresh_entry , plant delta 410 epsilon 510 _parent_entries --,:=AS^IS:^:bypath:granddad , save dad
axs03 fresh_entry , plant lambda 7000 mu 8000 _parent_entries --,:=AS^IS:^:bypath:dad,AS^IS:^:bypath:mum , save child
assert 'axs03 bypath child , substitute "#{alpha}#+#{beta}#, #{gamma}#-#{delta}#, #{epsilon}#*#{lambda}#"' '10+200, 31-410, 510*7000'
assert 'axs03 bypath dad , get multisub2 --delta=411 --zeta=611' "['31-411', '510-611']"

All commands run correctly.

2. Run the following command:

maria@axel:~/axs03$ axs03 d: bypath dad , dig d.multisub2.1 --epsilon=3333
