Bug Fixes 

When create PDF activity is executed without selecting input files, then a junk PDF was created as output. Additional validation has been included to prevent this.

In create PDF and Merge PDF activities, when the input for files to be merged is defined in numbers then the output file contained duplicate pages. Example when the files to be merged are (1.jpg, 2.png, 3.jpg) then the output contained two pages of 1.jpg and 3.jpg was missing in the output file.
