order-based params need to be trimmed

demonstrating the problem: this is taken directly from the doc page, plus break into multi-line, which is the preferred "format" for multi-param templates:

{{WikidataChart
|P1087
|P585
|pageIds=Q106807, Q217198
|xEnd=2015
|chart_width=600
|chart_height=200
|chart_legend=Legende
|chart_yGrid=1
}}

<graph>Lua-Fehler in Modul:WikidataChart, Zeile 32: attempt to index local 'entity' (a nil value)</graph>

this is easy to solve: add around line #12 of Modul:WikidataChart

property = mw.text.trim(property)
xQualifier = mw.text.trim(xQualifier)
