expansion does not work for keywords when another tree is referenced in the .cli file

[DeekshaBhandary]

Issue is seen when redundant keywords are present in the referenced tree at the same hierarchy

consider tree syntax : file:op.cli treename= "op"; show { word1; word2; }

file : test.cli show { word3; word4; } @op;

cli: op> show <PRESS ?>
word1
word2
cli :op>

cli: cfg><PRESS ?>
show
show                    <------------------ duplicate keywords
cli: cfg> show <PRESS ?>     <-------------------no suggestion are seen

Expected behaviour :

cli: cfg> show <PRESS ?>
word1
word2
word3
word4
cli: cfg>

Related to https://github.com/clicon/clixon/issues/301 but somewhat larger in that not only duplicate keywords but also no expanded suggestions are seen. As with #301 it worked in 5.3 but is broken in 5.4 and 5.5
