fix: Serial Nos not set in the row after scanning in popup

[marination]

Issue:

• In Delivery Note/Sales Invoice with update stock, etc. don't add warehouse (parent field)
• Add a serialised item code. Popup appears
• Add serial nos simulating a scanner. At the end press enter (go to next line), then click insert
• Serial nos are not set in the Item row
• The issue actually occurs on warehouse trigger.
• In this case since warehouse is not set in the row beforehand, warehouse is set from the popup after clicking on Insert
• In this trigger if the length of the serial nos in the popup text box != the qty, it clears the serial nos field
• Umm why was the length not equal? Remember this => At the end press enter (go to next line ? The culprit.
• This causes serial_nos = ['123', '456', '']. Ideally the length here is 2, but the extra string makes the length 3. Hence not equal to length, hence empty field
  

Fix:

• Filter out empty strings and whitespaces to get the exact length of serial nos
• This issue happens even if extra line is added in serial no text box (not in popup) and warehouse is changed, so handled it at warehouse trigger.
