Reports wrong number of quotes around parameter in property value.
If parameters are present in the property value, then the value would be passed as pattern to `java.text.MessageFormat`. This means that single quotes would be used for escaping and in order to keep a quote visible one need to double it.

'{0}' → {0}
''{0}'' → '$value$'

When choice format is used, nested formats are evaluated as formats themselves and second dbl quotes are required. If 1 is passed:

{0, choice, 0#no|#1''{0}'' file} →{0} files
{0, choice, 0#no|#1''''{0}'''' file} →'$number_of_files$' files
