<browser>: Always read <browser>.src attribute from <object>.src.

Browse Source 
If we navigate to 'http://www.google.com', then navigate to '' (empty src), reading <browser>.src would now give us (expected) 'http://www.google.com' since we ignore setting empty src attribute in browser_plugin.cc.

BUG=149001
TEST=In web inspector, setting src on <browser> element and reading it.
Added platform app test for verifying the change.
Ran content_browsertests for BrowserPluginTest* and BrowserPluginHostTest*
