Permission related pages should reset pageNum when searching

[maoling]

• How to reproduce this bug:

  Suppose that I have 10 pages users data, when I jump to page 4, then I search username like "bob"
  then I search for nothing, in fact the data in the page 2, the parameter pageNo should
  be reset to 1, not 4.

• The paging backend api seems not to work, I'll create another PR to fix it.
