Server Demo: writing "" empty strings (e.g. cancel firmware update)

[boaks]

Writing an empty string ("") to /5/0/1 to cancel a firmware update is suppressed.
No request is sent.
According the LWM2M TS, appendix E.6,

If writing an empty string to Package Resource is done or writing an empty string to Package URI is done, the state changes to Idle.

it seesm to be considered as "valid operation" (even if there may be a discussion on what "mandatory" means :-) )

As far as I understand, the write is suppressed in
"resource-directives.js", line 152,

if(value) {

changing that to

if(value || "" == value) {

would allow to write an empty string.
