fix(semantic-scholar): filtered by url for existing manuscripts in colab
Issue addressed #1077 (closed)
The existing manuscripts in colab instance were having URL in the form of https://doi.org/DOINUMBER, and the DOI column in manuscript table was empty, due to which import from semantic scholar was getting duplicated. I have added a fix, filtering out the imports by checking if the URL is similar to https://doi.org/DOIFROMSEMANTICSCHOLAR, and discarding those manuscripts.
