buildinfohelper: fix retrieval of targets

When buildinfohelper records the targets for a build, it looks
up any existing targets for a build and creates them if they
are not present. This is because in the case of Toaster-triggered
builds, the Target objects have already been created (inside
triggerBuild()) and don't need to be recreated; but in the case
of cli builds, the Target objects have to be created by
buildinfohelper.

The issue is that the code for retrieving an existing target for
a build only looks for Targets with a matching target and build,
e.g. Targets for build X with target "core-image-minimal". But it
is perfectly legitimate to call bitbake with a command like
"bitbake core-image-minimal:do_populate_sdk
core-image-minimal:do_populate_sdk_ext". In such a case, the
code which looks for matching targets finds two objects, as it
doesn't filter by task.

Add the task into the filter for the Target so that only one
Target object is be returned. Note that a command
line like "bitbake recipe:task recipe:task" will still cause an
error as bitbake doesn't de-duplicate the command line arguments
and will run the recipe:task combination twice.
