improvements to user/getTest

[srijondasgit]

• Move all components of "getTest" header section to the center of the page -Provide a light background as in the register page on https://gitanjali.org/register Create a line separator between "create test" and teacher's list of tests as seen in https://gitanjali.org/school
• use text type and color to match gitanjali.org/school
• the text length of the fields in the table is changing. fix the max length of characters in the fields to (say) 5 for index, 500 for question text(but it should wordwrap within a specified length), 5 for score and fixed length for delete button
