        <Strings>
          <ButtonText>TestMenu</ButtonText>
          <CommandName>TestMenu</CommandName>

You should sets <Parent guid="guidSHLMainMenu" id="IDM_VS_CTXT_SOLNNODE" /> in one group instead of one menu.

Change it from:

<Groups>
  <Group guid="guidVSIXProject1PackageCmdSet" id="MyMenuGroup" priority="0x0600">
    <Parent guid="guidVSIXProject1PackageCmdSet" id="TopLevelMenu"/>
  </Group>
</Groups>

To:

<Groups>
  <Group guid="guidVSIXProject2PackageCmdSet" id="MyMenuGroup" priority="0x0600">
    <!--<Parent guid="guidVSIXProject2PackageCmdSet" id="TopLevelMenu"/>-->
    <Parent guid="guidSHLMainMenu" id="IDM_VS_CTXT_SOLNNODE"/>
  </Group>
</Groups>

This will move your menu from Extensions top menu to Solution context(right-click solution).

But this also means you can't find the command from top-menu any more, if you want to make the command available both in Top-menu and Solution context, please consider using CommandPlacements.
