[BUG] clean up uri / docUri parameters

[daniel-jettka]

Describe the problem
While reactivating the help window it became apparent that there is an inconsistency in the use of the uri / docUri parameters in the pipeline extJS view -> xql -> xslt
This was not solved in #470 and should be cleaned

To Reproduce
Relevant places:
HelpWindow.js - https://github.com/Edirom/Edirom-Online/blob/develop/app/controller/window/HelpWindow.js#L45
getHelp.xql - https://github.com/Edirom/Edirom-Online/blob/develop/add/data/xql/getHelp.xql#L41
teiBody2HTML.xsl - https://github.com/Edirom/Edirom-Online/blob/develop/add/data/xslt/tei/profiles/edirom-body/teiBody2HTML.xsl#L13

Expected behavior
Either pass a useful URI from HelpWindow.js or strip the parameter completely from teiBody2HTML.xsl
