bug: pagination - clicking Next when using ?size=n uses the default size

[imarudina]

When using custom size:
http://localhost:8080/admin/submission/view?size=5

clicking on Next leads to:
http://localhost:8080/admin/submission/view?page=1

Custom size is lost and the application displays the next 20 submissions page skipping 20 submissions.
In case the initial number of submissions is less than 20, clicking Next leads to an empty table.

the next should always include the custom size if such has been provided as ${param.xxxx}
