Updated location information doesn

[forslund]

Steps to reproduce:

Import a po file like:

# HEADER
msgid ""
msgstr ""
"Project-Id-Version: PACKAGE VERSION\n"
"Report-Msgid-Bugs-To: \n"
"POT-Creation-Date: 2019-02-07 10:17+0000\n"
"PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n"
"Last-Translator: FULL NAME <EMAIL@ADDRESS>\n"
"Language-Team: LANGUAGE <LL@li.org>\n"
"Language: \n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"X-Generator: Translate Toolkit 2.2.5\n"

#: myfile.txt:1
msgid "this is my file"
msgstr ""

Then modify the location tag to a new filename without changing the msgid:

# HEADER
msgid ""
msgstr ""
"Project-Id-Version: PACKAGE VERSION\n"
"Report-Msgid-Bugs-To: \n"
"POT-Creation-Date: 2019-02-07 10:17+0000\n"
"PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n"
"Last-Translator: FULL NAME <EMAIL@ADDRESS>\n"
"Language-Team: LANGUAGE <LL@li.org>\n"
"Language: \n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"X-Generator: Translate Toolkit 2.2.5\n"

#: myfile.md:1
msgid "this is my file"
msgstr ""

Run pootle update_stores for the project.

Results (Expected/Actual):

Expected result: the location field / comment in the pootle db should be updated to reflect the new location.

Actual result: No change is detected and pootle still uses the old location.

Environment (i.e. 'pootle --version', DB, OS, Browser):

pootle --version
Pootle 2.8.2 (Django 1.10.8, Translate Toolkit 2.2.5)
